Clickwheel and Center Button

5th Generation

The 5th generation iPod uses a plastic front panel, and the click wheel was designed to sit flush with that plastic surface. The center button was also designed to match the height and profile of this click wheel.

Our housings are designed so that the 5th generation click wheel sits flush with the front surface, maintaining a clean and original-style appearance.


The 6/7 Generation

When Apple introduced the 6th and 7th generation iPods, they switched to a metal front panel instead of the plastic front used on the 5th generation models. Because the metal front is thinner, the surface of the iPod sits closer to the internal electronics.

To accommodate this change, Apple redesigned the click wheel assembly. The click wheel became slightly thinner and the center button profile changed to match the new geometry.

Our MKII housing uses a revised center button designed for the 6th/7th generation click wheel. When using this combination, the click wheel may sit slightly recessed (inset) relative to the front surface. This is normal and does not affect functionality. The chamfer around the click wheel opening on our front panel ensures smooth operation and good usability.

For advanced users, another option is to transplant the internal electronics from a 6th/7th generation click wheel into the plastic shell of a 5th generation click wheel. This hybrid approach allows the click wheel to sit flush with the Boxy Pixel front panel while still maintaining compatibility with 6th/7th generation hardware
